* First pass updating misc files, informed by https://github.com/pybind/pybind11/pull/5177/commits * Remove jobs using silkeh/clang and gcc docker containers that come with Python 3.7 * Add silkeh/clang:17-bookworm * Add job using GCC 7 * Revert "Add job using GCC 7" This reverts commit518515a761
. * Try running in ubuntu-18.04 container under ubuntu-latest (to get GCC 7) * Fix `-` vs `:` mixup. * This reverts commitb1c4304475
. Revert "Try running in ubuntu:18.04 container under ubuntu-latest (to get GCC 7)" This reverts commitb203a294bb
. * `git grep 0x03080000` cleanup. * `git grep -I -E '3\.7'` cleanup. Removes two changes made under pybind/pybind11#3702 * Revert "`git grep -I -E '3\.7'` cleanup." This reverts commitbb5b9d187b
. * Remove comments that are evidently incorrect: ``` ... -- The CXX compiler identification is Clang 15.0.7 ... - Found Python: /usr/bin/python3.9 (found suitable version "3.9.2", minimum required is "3.7") found components: Interpreter Development.Module Development.Embed ... /__w/pybind11/pybind11/include/pybind11/gil.h:150:13: error: 'auto key' can be declared as 'auto *key' [readability-qualified-auto,-warnings-as-errors] auto key = internals.tstate; ^~~~~ auto * /__w/pybind11/pybind11/include/pybind11/gil.h:174:13: error: 'auto key' can be declared as 'auto *key' [readability-qualified-auto,-warnings-as-errors] auto key = detail::get_internals().tstate; ^~~~~ auto * ``` * .github/workflows/configure.yml: Change from Python 3.7 to 3.8 * Misc cleanup pass * Miscellaneous changes based on manual review of the `git grep` matches below: ``` git_grep_37_38.sh |& sort | uniq -c ``` With git_grep_37_38.sh: ``` set -x git grep 0x0307 git grep 0x0308 git grep PY_MINOR_VERSION git grep PYPY_VERSION git grep -I -E '3\.7' git grep -I -E '3\.8' git grep -I -E '\(3, 7' git grep -I -E '\(3, 8' git grep -I -E '3[^A-Za-z0-9.]+7' git grep -I -E '3[^A-Za-z0-9.]+8' ``` Output: ``` 1 .appveyor.yml: $env:CMAKE_INCLUDE_PATH = "eigen-3.3.7;$env:CMAKE_INCLUDE_PATH" 1 .appveyor.yml: 7z x eigen-3.3.7.zip -y > $null 1 .appveyor.yml: Start-FileDownload 'https://gitlab.com/libeigen/eigen/-/archive/3.3.7/eigen-3.3.7.zip' 1 CMakeLists.txt: # Bug in macOS CMake < 3.7 is unable to download catch 1 CMakeLists.txt: elseif(WINDOWS AND CMAKE_VERSION VERSION_LESS 3.8) 1 CMakeLists.txt: if(OSX AND CMAKE_VERSION VERSION_LESS 3.7) 1 CMakeLists.txt: message(WARNING "CMAKE 3.7+ needed on macOS to download catch, and newer HIGHLY recommended") 1 CMakeLists.txt: message(WARNING "CMAKE 3.8+ tested on Windows, previous versions untested") 1 CMakeLists.txt: # Only tested with 3.8+ in CI. 1 docs/advanced/functions.rst:Python 3.8 introduced a new positional-only argument syntax, using ``/`` in the 1 docs/changelog.rst:* Adapt pybind11 to a C API convention change in Python 3.8. `#1950 1 docs/changelog.rst:* Allow thread termination to be avoided during shutdown for CPython 3.7+ via 1 docs/changelog.rst: considered as conversion, consistent with Python 3.8+. 1 docs/changelog.rst: CPython 3.8 and 3.9 debug builds. 1 docs/changelog.rst:* Enum now has an ``__index__`` method on Python <3.8 too. 1 docs/changelog.rst: on Python 3.8. `#1780 <https://github.com/pybind/pybind11/pull/1780>`_. 1 docs/changelog.rst:* PyPy 3.10 support was added, PyPy 3.7 support was dropped. 2 docs/changelog.rst:* Support PyPy 7.3.7 and the PyPy3.8 beta.
